1 简介

本文档介绍了流量监管的配置举例。

流量监管就是对流量进行控制,通过监督进入网络的流量速率,对超出部分的流量进行“惩罚”,使进入的流量被限制在一个合理的范围之内,以保护网络资源和运营商的利益。

流量监管分为:聚合CAR和普通CAR。聚合CAR是指能够对多个端口上的业务流使用同一个CAR进行流量监管,即如果多个端口应用同一聚合CAR,则这多个端口的流量之和必须在此聚合CAR设定的流量监管范围之内。普通CAR与聚合CAR不同,在端口上应用的普通CAR无法实现对多个端口的流量之和进行流量监管,不同端口上应用的普通CAR需要单独配置。

2 配置前提

本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。

本文假设您已了解流量监管特性。

3 基于IP地址和协议类型进行流量监管典型配置举例

3.1  组网需求

图3-1所示,某公司网络通过专线接入Internet,上行带宽为60Mbps,所有终端设备均以防火墙作为网关设备。现要求使用流量监管功能,对上行至Internet的流量进行分类限速:

·     HTTP流量:总上行限速为40Mbps,其中研发部25台主机分配15Mbps上行带宽;市场部40台主机分配25Mbps上行带宽。

·     邮件服务器代理所有客户端向外网发送电子邮件,限制上行带宽为2Mbps。

·     远端分支机构可以通过Internet访问FTP服务器,限制上行的FTP的数据流量不超过10Mbps。

图3-1 基于IP地址和协议类型进行流量监管配置组网图

 

3.2  配置思路

要实现对不同特征数据流的流量监管,主要是明确匹配各业务数据的类规则。在本例中,需要使用ACL来匹配各种协议或来源的IP报文,并将这些分类规则与不同的流量监管动作进行绑定,即可实现对不同特征的数据进行不同的速率限制。

3.3  使用版本

本举例是在S3210-CMW710-R7566版本上进行配置和验证的。

3.4  配置注意事项

在一个流行为中,流量监管动作不能与重标记优先级(包括本地优先级、丢弃优先级、802.1p优先级、DSCP优先级、IP优先级)的动作同时配置,否则会导致该流行为不能被正常应用。

[Device-acl-ipv4-adv-3002] quit

# 创建类email,匹配规则为IPv4 ACL 3002

[Device] traffic classifier email

[Device-classifier-email] if-match acl 3002

[Device-classifier-email] quit

# 创建流行为email,动作为流量监管,承诺速率为2Mbps。

[Device] traffic behavior email

[Device-behavior-email] car cir 2048

[Device-behavior-email] quit

# 创建QoS策略email&ftp。

[Device] qos policy email&ftp

[Device-behavior-ftp] quit

# 在QoS策略email&ftp中为类ftp指定流行为ftp。

[Device] qos policy email&ftp

[Device-qospolicy-email&ftp] classifier ftp behavior ftp

[Device-qospolicy-email&ftp] quit

# 将策略应用到Ten-GigabitEthernet1/0/25端口的出方向。

[Device] interface ten-gigabitethernet 1/0/25

[Device-Ten-GigabitEthernet1/0/25] qos apply policy email&ftp outbound

[Device-Ten-GigabitEthernet1/0/25] quit

4 聚合CAR典型配置举例

4.1  组网需求

图4-1所示,某企业内部包含研发和市场两大部门,其中,研发部又分成研发部一部和研发部二部,各部门通过Device设备接入Internet。现企业要求在Device上配置聚合CAR功能对研发部访问Internet的总带宽进行限速,上行和下行的带宽都不能超过10M。

图4-1 聚合CAR配置组网图

 

4.2  配置思路

为了实现研发部访问Internet的上行和下行带宽都不超过10Mbps,可以在internet与Device连接的端口XGE1/0/25的出入方向上分别配置聚合CAR对上下行流量进行监管。
